Why I did it
Recent systemd upgrade from #7228 requires an extra cmdline parameter for dockerd to start properly.
Updating boot0 was missed as part of the systemd upgrade change.
How I did it
Just added the missing cmdline parameter in files/Aboot/boot0.j2
This change fixes#7372
How to verify it
Boot the image and dockerd should start normally.

- Miscellaneous fixes
A few issues where discovered with crashkernel on Arista platforms.
1) platforms using `docker_inram=on` would end up OOM in kdump environment.
This happens because the same initramfs is used by SONiC and the crashkernel.
With `docker_inram=on` the `dockerfs.tar.gz` is extracted in a `tmpfs` created for the occasion.
Since `dockerfs.tar.gz` weights more than 1.5G, it doesn't fit into the kdump environment and ends up OOM.
This OOM event can in turn trigger a panic.
2) Arista platforms with `secureboot` enabled would fail to load the crashkernel because the kernel parameter would be discarded on boot.
This happens because the `boot0` in secureboot mode is strict about kernel parameter injection.
3) The secureboot path allowlist would remove kernel crash reports.
4) The kdump service would fail on Arista products since `/boot/` is empty in `secureboot`
**- How I did it**
1) To prevent an OOM event in the crashkernel the fix is to avoid the codepaths in `union-mount` that create tmpfs and populate them. Some more codepath specific to Arista devices are also skipped to make the kdump process faster.
This relies on detecting that the initramfs is starting in a kdump environment and skipping some initialization.
The `/usr/sbin/kdump-config` tool appends a few kernel cmdline arguments when loading the crashkernel.
The most unique one is `systemd.unit=kdump-tools.service` which is used in a few initramfs hooks to set `in_kdump`.
2) To allow `kdump` to work in `secureboot` environment the cmdline generation in boot0 was slightly modified.
The codepath to load kernel parameters changed by SONiC is now running for booting in secure mode.
It was altered to prevent an append only behavior which would grow the `kernel-cmdline` at every reboot.
This ever growing behavior would lead `kexec` to fail to load the kernel due to a too long cmdline.
3) To get the kernel crash under /var/crash this path has to be added to `allowlist_paths`
4) The `/host/image-XXX/boot` folder is now populated in `secureboot` mode but not used.
**- How to verify it**
Regular boot:
- enable kdump
- enable docker_inram=on via kernel-params
- reboot
- generate a crash `echo c > /proc/sysrq-trigger`
- before: witness OOM events on the console
- after: crash kernel works and crash available under /var/crash
Secure boot:
- enable kdump
- reboot
- generate a crash `echo c > /proc/sysrq-trigger`
- before: witness no kdump
- after: crash kernel works and crash available under /var/crash

To limit IO and space usage on the flash device the boot0 script makes sure the SWI is in memory.
Because SONiC maps /tmp on the flash, some logic is required to make sure of it.
However it is possible for some provisioning mechanism to already download the swi in a memory file system.
This case was not handled properly by the boot0 script.
It now detect if the image is on a tmpfs or a ramfs and keep it there if that is the case.
The cleanup method has been updated accordingly and will only cleanup
the mount path if it's below /tmp/ as to not affect user mounted paths.
- How I did it
Check the filesystem on which the SWI pointed by swipath lies.
If this filesystem is a ramfs or a tmpfs the move_swi_to_tmpfs becomes a no-op.
Made sure the cleanup logic would not behave unexpectedly.
- How to verify it
In SONiC:
Download the swi under /tmp and makes sure it gets moved to /tmp/tmp-swi which gets mounted for that purpose.
Make sure /tmp/tmp-swi gets unmounted once the install process is done.
Create a new mountpoint under /ram using either ramfs or tmpfs and download the swi there.
Install the swi using sonic-installer and makes sure the image doesn't get moved by looking at the logs.
- Enhance eeprom parsing robustness on corrupted fields
- Add chassis provisioning service
- Disable CPU sleep state on some systems
- Complete refactor for FanSlots
- Fix module unload while still in use
Current support for the 7060PX4-32 and 7060DX4 was broken.
With this change, ports are now linking fine.

* Add secureboot support in boot0
* Initramfs changes for secureboot on Aboot devices
* Do not compress squashfs and gz in fs.zip
It doesn't make much sense to do so since these files are already
compressed.
Also not compressing the squashfs has the advantage of making it
mountable via a loop device.
* Add loopoffset parameter to initramfs-tools
* Support rw files allowlist for Sonic Secure Boot
* Improve the performance
* fix bug
* Move the config description into a md file
* Change to use a simple way to remove the blank line
* Support chmod a-x in rw folder
* Change function name
* Change some unnecessary words
Fix the issue of incorrectly skipping the convertfs hook when fast-reboot from EOS, by adding an extra kernel cmdline param "prev_os" to differentiate fast-reboot from EOS and from SONiC.
This is because we still do disk conversion for fast reboot from eos to sonic, like format the disk.

when device disk is small, do not unzip dockerfs.tar.gz on disk.
keep the tar file on the disk, unzip to tmpfs in the initrd phase.

* Fix showing systemd shutdown sequence when verbose is set
* Fix creation of kernel-cmdline file
Sometimes boot0 prints error
"mv: can't preserve ownership of '/mnt/flash/image-arsonic.xxxx/kernel-cmdline': Operation not permitted"
* Improve flash space usage during installation
Some older systems only have 2GB of flash available. Installing a second
image on these can prove to be challenging.
The new installation process moves the installer swi to memory in order
to avoid free up space from the flash before uncompressing it there.
It removes all the flash space usage spike and also improves the IO
since the installation is no more reading and writting to the flash at
the same time.
* Add support of 7060CX-32S-SSD

Some platform plugin need the python smbus library to perform some actions.
This installs the dependency.
* Update arista drivers submodule

* Add verbosity toggle to boot0
Console logging is slow because of the 9600 baud rate.
Some time can be saved by decreasing the console verbosity.
* Add hook mechanism in boot0.
Support additional features in boot0 via hooks.
Hooks are unpacked and executed at post-install or pre-exec time.
* Fix 7170 sensors.conf file
Fix critical temperature settings for MAX6658 sensors
* Fix the random swap of storage devices
For arista 7050 switches running with linux 4.9, it is likely the device
name of flash drive (/dev/sda) and usb (/dev/sdb) randomly swap in kernel
booting, depending on which one is ready first. It breaks the expectation
that flash will be mounted as root by setting root=/dev/sda1. This patch
will correct ROOT to flash device refering to the path under block_flash.
* Fix 7170 fancontrol
* Do not remove aquota.user file in boot0
This file is a filesystem protected file used by EOS.
It can be simply removed and will make the SONiC installation failed if
not skipped.
Currently setting the next boot image is the same as setting a default
image.
With this change SWI_DEFAULT= will be considered the default image and
SWI= the next image.
When executing the boot0 SWI= will be overriden by SWI_DEFAULT= if it
exists and create in with the value of SWI= otherwise.
On overlay filesystem the name of the mountpoint will also match in the
mount command for overlayfs as upperdir=
To prevent detecting the wrong partition we now look for space before.
This ensure that we match mountpoint and not devices in df and mount
outputs.
Now properly differenciate the image installation and the kexec
operations. This is useful for fast-reboot operations.
Minor updates include
- better command line management
- using partition UUID in the command line
